To all whom it' may concern.- V

Be it known that I, HAROLD G. MARTIN, of

the city and county of Providence, in the State ofRhode Island, have'invent'ed an ImprovemeritinBicycle-Bells; andl declare the following to be a specification thereof, reference being had to the accompanying .drawin,g ;s.v

My. invention relates. to that class of hicycles in which the soundingof the bell is due to the frictional contact of thevwheelof tions.

It consists, ver pivotedon a stationary disk or plate, said lever to operate the friction-roller and adapt-- 4 and out of engagement with ease and rapidity.

Figure 1 represents a side elevationwith the sounding-bell removed. Fig. 2 is a top sectional View in linear a: of thesanie. Fig. 3 is a top view of the friction-roller with shaft and operating-levenwith the conne'otingde- Ver sleeve, and inner-cylinder casing shown in central section. Fig. iis a cross-sectional view iniine y 'y of the same. Fig. 5 is a crosssectional view in line 2 z of Fig. 2, showing the arrangement of the parts 'vrhen the frie tion-roller'is in contact with the rim ortire of the wheel. Fig. 6 is a rear elevation of the disk orplate with the operating-lever and its connection with the rollershaft Fig. 7 is a top sectional view of the clamping device.

. Like letters indicate like parts.

' A isa front fork of a bicycle, and W is a portion of the rim or tire of its front wheel.

0 is the bell-supporting bracket, whichconf sists of an arm attached to the rear side of the disk or plate D and having its lower end of a channel form, into which the band a, which hooks around the fork A, is inserted.

The inner ends of said band are made to overlap one another, and an adjusting-screw b,

5o-'which fits loosely in the flange of the bracket O, engages with .theoverlapping ends of the the machine with power-transmitting connec-v essentially, in an operating-leband and draws the same firmly to the fork Act the machine. (See Fig. 7.) In referring to Fig. 1, which shows the operative parts of my improvement as applied to the maohin'.e-'

projecting stud 0, upon the end of which the bell E is' secured by a screw d and which supports said-hell in a vertical position to one side of the rim of the wheel.

The disk or plate D lies within the inner side of the bell, said bell forming acover' thereon, though without touching it, (See Fig. 2.) On'the rear side of the plateD and pivoted thereon at f is the operating-lever 6. (See Fig. 6.) This operating-lever connects at g with a secondary lever 71, which is provided with a hollow sleeve or hub i, extending outwardly froinits upper end,- and said sieeve carries the friction-roller shaft j. This shaft j has its inner end 7:; of a greater diameter, and this enlargement has a circumfercntial slot 1, extending around about onehalf the cylindricai enlargement of said shaft. A

casing in fits loosely over the portion 7a, and a pin n is inserted. through the casing and which engages in the slot Z, as hereinafter particularly described. 7

The sleeve 2' of the secondary lever Works up and down in the slotted opening 0, formed in the plate '1), by the operating-lever e and brings the friction-roller (H in contact with the rim of the wheel. Carried by the plate D is the swinging hammer 10, adapted to strike the bell. Said hammer is provided with a spring-rod attached thereon and having its uppercnd secured to the plate by a clampsorow r.

A rod 5 connects from the front side of the casing m to about midway of the hammerspring, and by the revolving of the shaft j, the friction-roller being in contact on the rim of the wheel, the slotted end [of said shaft draws the pin 91, attached to the casing m, around till it arrives at the position shown in Fig, 5, where the hammer-springattached to the disk acts upon the loose casing and causes it to travel to the position shown in lution of the shaft. I

D is the stationary disk 'or plate, mounted on a bracket C, said plate having a centrally- A pin tis secured to the operating-lover c and projects through a slotted opening a in theplate D, and a coil-spring n is made fast to said pin and extends upward to a fixed pin in the plate, said main spring being," for the purpose of keeping the friction-roller out of contact of the rim of the wheel.

The operation of myimproved bicycle-bell is as follows: The disk or plate Dis stationary and holds the bell in a fixed position at all times by the clamping-bracket a, secured to the fork of the machine.

By pressing on the lever G pulls on the wire to and brings the operating-lever e upward and carries down the frictionroller in contact with the rim of the heel. The shaft j thereby revolves and with the enlarged slotted endk of said shaft j carries the pin 71 with it, and at each and every revolution of the shaft the hammer-spring attached to the hammer forward and producing a rapid succession of blows on the bell.

As soon as the hand-lever is released the main spring U returns the parts to their inoperative position, seen in Fig. vl..;

Having thus described my invention, what I claim as new, and desire to'secnre'by Letters Patent, is

The combination, with a-= -hell, supported from the frame of a bicycle, having-a stationary disk or plate D, with an foperatinzi,

lever e pivoted thereon, a ndcarny1.ng'.tne-

friction-roller shaft mounted tosWing on said plate, the shaftj having its inner end 70 of an enlarged diameter and provided with a circumferential groove or slot 1, a casing m loosely fitted over the enlargement of said shaft, with the pin a to engage in the slotted opening of the same, a spring-controlled hammer attached to the plate, with a connection therefrom to the side of the casing and eccentric thereto, and means for throwingthe friction-roller into and out of contact with the
